CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 754,027,- dated March8, 1904.

Application filed June 19, 1903. Serial No. 162,165. (No model.)

To all whom it may concern.-

Be it known that I, HENRY TESSEYMAN, a citizen of the United States, anda resident of the city of Dayton, in the county of Montgomery and Stateof Ohio, have invented certain new and useful Improvements inCar-Trucks;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and usethe same, reference being hadto the accompanying drawings, and to the figures of reference markedthereon, as forming a part of this specification.

My invention relates to improvements in car trucks, more particularly tothe class known as steel passenger-car trucks.

The invention has for its object to provide increased space between theside frames of the truck and the body of the car, whereby freer accessfor the purpose of examination and repairs is given and whereby thedepth of the body-bolster can be increased for the purpose of addingstrength thereto when required for extra heavy cars without raising thecar-body.

A further object of the invention is to provide additional room forpiping and other appliances.

To these ends the invention consists in the construction, combination,and arrangement of parts, as hereinafter fully described,pointed out inthe claims, and which are fully illustrated in the accompanyingdrawings, of which Figure 1 is a perspective view of a car-truckembodying my said improvements. Fig. 2 is a broken verticalcross-section through line X X of Fig. 1 with the equalizer-springs,spring seats and brackets, and the journalboxes removed. Fig. 3 is aView showing a partial side elevation and partial longitudinalcross-section through the center of the truck. Fig. 4 is a brokenperspective view of the truck-transom detached from the truck. Fig. 5 isa broken perspective view of the springplank and bearing for theswing-motion axle, and Fig. 6 is a broken perspective View of theswing-motion hanger and swing-motion axle detached.

In construction both sides of the truck are alike. Therefore in thedrawings and following description reference need only be made to oneside thereof.

Similar reference-numerals indicate corresponding parts in all thefigures of the drawings.

The side frames of the truck are each composed of a sheet of iron orsteel 1, stiffened by angle-irons 2, 3, 4, and 5, riveted or boltedthereto around the edges on both sides thereof. These side frames arecut out at 6 to receive the journal-boxes 7 andat 8 to receiveequalizer-springs 9 and at 10 to receive elliptic or bolster springs 11,as shown in Fig. 1. The openings or cut-outs 6 and 10 are provided withcastings or forgings 12 13, riveted or bolted to the side frames for thepurpose of strengthening the latter, and without some such strengtheningmeans to compensate for the material so cut away the side frames wouldnot be of sufficient strength to perform their functions satisfactorily.The cut-outs 8 may also be strengthened in a similar manner where it isdeemed advisable. The castings 12 are usually termed pedestals, and theyform guides in which the journal-boxes move. The

side frames are united at their ends by end sills l t by means ofbrackets 15, and when thus united these several parts constitute what iscommonly known as the truck-frame.

16 represents equalizers, there being four to each truck, (one on eachside of the two side frames,) and they are formed to the shape shown,their ends resting in grooves formed in the tops of the journal-boxes.Spring-seats 17 are mounted upon both equalizers at equal distances fromthe center thereof, and in or upon these seats the lower ends of theequalizer-springs rest, their upper ends being provided with caps 18,which bear against brackets 19 and 20, secured to the side frames onboth sides thereof, the inside bracket 20 being arranged to receive theends of and to carry crossbars 21, which carry the brake mechanism.

At the center of the truck between the side 7 frames there is located atruck-bolster 22, provided with the usual side bearings 23 and centerplate 2 1. This bolster is connected with and carries the car-body inthe usual manner, and it may be of any preferred construction. At eachside of the truck-bolster and in near proximity thereto there isarranged a trucktransom 25, which in order to obtain maximum strengthwith minimum weight I prefer to make of a single piece of metal formedto resemble in cross-section an inverted letter U, with the ends of theside portions extending at right angles thereto and forming flanges 26,by which the said transoms are riveted or bolted to the side frames, asshown.

The truck-bolster, at each end thereof, is mounted on the elliptic orbolster springs 11, which in turn are mounted upon a springplank 27,preferably made of two angle-irons connected at each end byconnecting-castings 28, which are provided with a bearing 29 for aswing-motion axle 30, the latter being suspended from theZtruck-transomsby means of a pair of swing-motion hangers 31, which oscillate onswing-motion pins 32, having their bearings in the side portions of thetruck-transoms, as more clearly shown in Fig. 3, the upper edge of theswing-motion axle being rounded to register with thecorrespondinglyrounded surface of the bearing 29, whereby the requisiteamount of horizontal movement of the spring-plank is permitted, theusual spring-seats 34L 35 being interposed between the spring and thetruck-bolster and springplank. To make more secure and strengthen theconnections between the ends of the trucktransoms and the side frames,strengtheningplates 36 are secured to these parts, and fillerplates 37are interposed between the side frames and the ends of the transoms, asshown.

It will be observed from the foregoing description that thetruck-transoms carry the entire weight of the car-body andtruck-bolster, the same being transmitted to the said transoms throughthe elliptic springs, the springplank, the sprin -motion axle, theswing-motion hanger, and the swing-motion pins, and it will beunderstood by those familiar with the art of car-building that in trucksas at present constructed room must be provided for action of theequalizer-springs between the upper side of the equalizer-feet and theunder side of the side frame of the truck, the latter being arrangedabove the former, while in my present invention the side frames, beinglocated between the equalizers and arranged as described and shown, arereduced in depth above the journal-boxes, thus lowering the truck-frameto the extent of the depth of the equalizer-feet and the difference indepth of the frame at this point; also, that the side frames can be madeof suflicient depths and the equalizers arranged to conform thereto toprovide for all necessary variation in capacity of equalizer-springs andfor the carrying of maximum load.

The foregoing is a general description of the truck shown in thedrawings, in which various details having no special reference to myinvention are omitted. It is to be understood, however, that thetruck-transoms instead of being formed of a single piece of metal may bemade of several pieces riveted together and that other details ofconstruction, as herein described, may be departed from withoutdeparting from the spirit of my invention.

Having thus fully described my invention, I claim and desire to secureby Letters Patent- 1. In a car-truck, the combination of side frameseach consisting of a sheet of metal having separate stiifening memberssecured thereto around the edges on both sides thereof, openings formedin the side frames, pedestals mounted in said openings and secured tothe side frames, journal-boxes operative within said pedestals, and anequalizer arranged on each side of the side frames and having their endssupported on the journal-boxes, substantially as shown and described.
